Hood Insulation - Keep or Toss?
Permalink  

When my car was restored they installed the underhood insulation package.  Although seen on the US cars, and while our hood does have the holes for the retainer clips, so far as I know it was never available in Canada, not even on the Grade Parisienne.

It's starting to fall down from time to time and I'm actually a little worried it might be a fire hazard if it comes down and sits on the manifold, for example.  Or is it flame proof?

I'm thinking I'm going to remove it.  Anyone have a strong opinion and/or reason to keep it?

I believe the only real purpose is to keep engine noise at bay (pardon the pun), right?

- Dave

 

PS: Our hoods also have the holes for the pins that prevent the hood from being driven back into the windshield in the event of an accident.  But they lack the pins!  Or at least my Laurentian does.  And in the one accident I've ever had in my life, the hood did in fact come straight back into the window!

It's fireproof, so no worries there. I've sometimes wondered if it helps preserve the paint on the hood but don't have any proof of that.

As far as being authentic I would agree, never on the Canadian Pontiacs, although I'm not up o 69 necessarily.

hood insulation's are non flammable. They were not volume item for us on the muscle  cars unless it was a Mopar. This changed once the cars got into the 1970's. The supplier claims one of the reasons to install  was for paint protection from engine heat. Both of my 442's came with hood insulation's,  but both were US built.

Protecting the hood from engine heat; I wonder if the prevalence of A/C and having places like Scottsdale, Needles & Death Valley had anything to do with the inclusion on U.S. cars. Certainly not the same environment in the Great White North (block heaters were must-haves in some locals).

You know I was going to toss it, then when people mentioned it might preserve paint I thought I might keep it, but then after my EFI installation, I'm sure I'm going to keep it. The injectors make a clicking sound, typical for injectors, that you can hear with the hood open but not closed. So I think it actually helps suppress that sound quite a bit, and it's helpful for that!

Unfortunately the full-size cars (US) only have non-molded repros. A body and G body Pontiac (US) have very nice repros that are molded.

I believe they were for noise abatement as they typically were not installed on the lowest priced models. If they were for paint protection theyd all have been equipped with them.

In 69 all US Pontiac models had them except for RamAir equipped GTO and Firebirds.
